Abstract

Procedure for the manufacture of a binder, by modifying the ureaformaldehyde resin with a low content of free formaldehyde, which is obtained in a three-stage condensation, alkaline, acidic and alkaline, with a general proportion of moles between urea and formaldehyde from 1: 1.2 to 2.5, characterized in that the resin is modified by active surface compounds or their aqueous solutions in an amount of 0.1 to 10% parts by weight in proportion to the initial amount of the resin.
